FEATURES OF COAL MINES DUMPS FLORA OF KEMEROVO REGION

Natural complexes of Kemerovo region are involved in the process of global anthropogenictransformation. The specificity of opencast mining is to move huge volumes ofsoil, to create new landscapes and to form new environmental conditions.The object of the research is the flora moldboard-mining landscapes, created as aresult of opencast mining. Field studies were conducted in the period from 1995 to 2008in 15 coal mines of Kuznetsk Basin, located within three climatic zones.The investigated flora includes 557 species from 293 genera and 80 families, representingabout 1/3 of the total flora of Kemerovo region. At dumps rare plants including12 species from the Red Book of Kemerovo region were found. At dumps 12 new species(Amelanchier alnifolia (Nutt.) Nutt., Elaeagnus angustifolia L., Erucastrum gallicum(Willd.) O.E. Schultz, Triticum aestivum L.; and 8 species: Achillea setacea Waldst. etKit., Chenopodium acuminatum Willd., Elymus excelsus Turcz. ex Griseb., E. trachicaulusssp. novae-angliae (Scribner) Tzvelev, Lotus sergievskiae R. Kam. et Kovalevsk., Rumexsylvestris (Lam.) Wallr., Sisymbrium wolgense Bieb. ex Fourn., Thesium arvenseHorvatovszky) were registered. These are mainly adventive species which reveal a tendencyof enriching the flora at the expense of adventive weed species invading the compositionof the flora with open areas of disturbed land.The originality of the species composition of Kuzbass coal dumps flora (ORSG == -30,9%). Species with wide ranges dominate in the flora. The Asian group is mostlyrepresented by forest and grassland species, the steppe component is very weak. The peculiarityof the biological spectrum is a high proportion of annual plants (23,4%). Theability of plants to vegetative reproduction plays a significant role, ¾ flora dumps beingable to clone. Specific feature of the flora is the predominance of meadow group speciesand a large percentage of forest and weed plants, steppe species are few.
